Floorplan in picture elements card, white highlight if I click anywhere that isnt a clickable light

I hope someone might be able to point me in the right direction please…
I’ve set up a floorplan using the picture elements card, which works really well except for one thing:

If I click outside of the clickable lights I’ve defined, I get a large round white highlight over the base picture I’ve used.
This:


becomes this (with the large white oval):

I’ve noticed that if I remove everything except for a single picture, it doesn’t happen… as soon as I add one of the aditional pictures of a room for a lights state, it does.
Only in browsers (firefox and edge), it doesn’t happen in the HA app on my android phone.

The whole card’s YAML is:

Is there something I’ve missed or done incorreclty somehow?

One other small thing I’ve found is that the HA app on my android phone doesnt seem to have kept up with some changes I’ve made to the pictures that are part of this. If it were a browser clearing/refreshing its cache would probably sort it, but I can’t find a way to do similar in the app. Clearing its cache doesnt make it pull through the current pictures…

Thanks a lot

I’m having the exact same issue. Not sure of the solution yet.
